| Abstract: | This paper deals with the nutritive mechanism and absorption process of mineral substances by Gastrodia elata The absorption actions on metal and non-metal elements by Armillariella mellea in Gastrodia elata are studied The absorption processes on organic nutrition are clarified Two paths of absorption of non-metal elements by Gastrodia elata are put forward “Pump”mechanism of absorption of metal elements by Gastrodia elata is analyzed The results also show that there are substances interchanges of free amino acids, especial aspartic acid and glutamic acid between Gastrodia elata and Armillariella mellea, and they are the key to growth and development of Gastrodia elata and Armillariella mellea |
